Just recently my phone shut down at 38% battery half an hour ago or so. It's brand new with a brand new battery and it hasn't happened since. I slipped and fell earlier and my phones corner made contact with the cement driveway I fell on but most of the fall was put on my arms and it has a speck case which is very very strong and durable. I'm just wondering if that may be a part of it and if this will continue to happen. Please comment your input.
